Oh sure, that's the sort of spin it gets. Still a helluva' thing, heh.
Not to be a downer (because I certainly appreciate the email irony going on), but people got their panties in a twist when they found out Hillary may have sent classified information over an unsecured email account, and then (again, this is what I witnessed) when they found that she absolutely did, and when the Democrat-led administration decided that no action would be taken, it hugely deepened the presupposition that she was an out-of-touch aristocrat who felt herself and her party was above the plebs/deplorables.
Politico says there is no indication that Kushner sent classified info, also it looks like it was just him responding to people sending him news articles?
Eh, people got their panties in a twist because people were screaming it was worth getting their panties in a twist about it, more than anything. Account was private, not unsecured, just (mostly?) not secured by department resources. What classified info was involved also involved other folks with clearance, and a near as people could tell, the stuff in question didn't seem to be particularly compromised (and not in the sort of "doesn't seem" our election infrastructure is involved with, where every few weeks someone comes back out and goes, "Hey, remember how we said it was only that bad? About that..."), so on, so forth. It was poor craft, so to speak, but far, far from catastrophically poor.
More, it's not like there's not more than one political figure that did things of near, equal, or worse magnitude on that front, with the same or less consequences for it, and a fucked up different degree of response. Some people might have legitimately been bugnut concerned about the infosec aspect, but it's hella' sketchy that was the primary cause of the response that was.
Any case, the kush thing seems mostly to be about who was involved and things said previously. Already forgot the details of this particular incident, but that lot has been having this thing happen with morbidly impressive frequency where they go "I totally didn't do that/didn't have communication with those people" (sometimes under oath, ha), and then a bit later stuff gets dug up that says, "Uh, no, you totally did, and we have copies or whatev' now."
Basically less a matter of infosec per se and more a matter of shit what we impeached a president for that one time. The emails comparison is probably more of a generalized go-fuck-yourself kinda' thing towards everyone (or at least everyone that's not torch and pitchforking with equal fervor for vaguely similarly or far more meaningful issues) that's been riding the butter, really. After goddamn months of being deluged with those emails, some folks are somewhat tetchy
